Does the amount of water affect energy levels and brain function?

Many people claim that if there is dehydration, energy levels and brain function start to deteriorate. And there are many studies that support this claim. A study in women showed that a loss of fluid of 1.36% after physical exercise impaired mood and concentration and increased the frequency of headaches (check out the study here: 1 ).

Other studies show that mild dehydration (1-3% of body weight) caused by exercise or heat can impair many other aspects of brain function ( 234 ). Remember that only 1% of body weight is a significant amount. This happens mainly when you are sweating a lot. Mild dehydration can also negatively affect physical performance, leading to a drop in resistance ( 567 ).
